I purchased a LK990 but the RBE is an issue for me currently. Am considering sending an offer for a used Rs4500, but with only 2600 lumens at max laser... I feel like I would also need to build a hush box and a paladin DCR to go with it.
On high bright, you can get the full 3000 lumens on high. I measured:
1308 low laser, high bright
2387 Mid laser, high bright
3204 high laser, high bright
High bright isn't very accurate.
If I move to BT709 then I get:
1090 low laser, bt709
1939 mid laser, bt709
2457 high laser, bt709
If you're using madVR to tone map HDR to SDR, you can get away with these lumen values on your large screen. Why don't you dump your 0.8 gain screen? It's cheaper to get an RS4500 and a new 1.4g screen or such than to get a sony 5000ES and keep your screen.
